Yum may trap you with its default settings. You might be better off downloading the desired kernel and installing with "sudo rpm -ivh kernel-xxx,xxx.rpm". > thank you Additional information: The default yum setting for the number of kernels to keep is 2. When you do an upgrade or install only the current kernel (the one that you are running) and the new kernel (one being installed ) will be left on your system. Any other kernels will be removed. If you want to keep more than just two you need to edit /etc/yum.conf and change the value of installonly_limit. Set the value to zero (0) if you want to keep all kernels that you have downloaded. (FC6 users need to edit /etc/yum/plugin.conf.d/installonlyn.conf and change the value of tokeep.)
